听力原文：M: Hi, Grace. Mind if I eat lunch with you? W: No. Mr. Evans, not at all. M: Thanks. I just heard that you're studying nutrition and you've got quite a bit of experience working in the cafeteria, so I wonder if you will be interested in a small project we are doing this term. W: What's the project all about? M: More and more students have been deciding not to buy the meal here and we want to attract them back. So I want to hear what students would like. Your job would be to find out. W: Well, if the menus were changed, then maybe I wouldn't have to listen to so much criticism. M: That makes you perfect for the job. Would you be interested? W: I'm not sure. What sorts of changes are you thinking of? M: I'd like to make some changes in the way we prepare our food. For example, just look at what we have to choose from today. You got a fried hamburger and I got fried chicken. They both contain too much fat. W: But you'd better not get rid of them. They're everybody's favorite. M: Well, we can certainly keep them, but we need to give the people who are health-conscious some choices. For example, we could also prepare chicken without the fatty skin and serve it on some rice with a light sauce. Do you think that would appeal to students? W: Well, I'd like that. You're right. You'd better find out what others think. Sorry, I've got to get back to work. I'd like to hear more though. I'll drop by your office later. M: Ok, see you then. (23)
